This packages defines two primary collection flavors:
Each map is java.util.Map adaptable.
-Core, stable abstractions for representing flow definitions. -
--Each flow has an indentifier and is composed of one or more states, one of which is the start state. -States may be transitionable, and if so define one or more transitions that lead to other states. -
--With these types a client can introspect a flow definition to reason on its attributes and traverse -its structure, perhaps to display a visual diagram. Note that the types defined in this package -do not capture the behavioral characteristics of a flow. -
--The following code shows the beginnings of a basic flow definition traversal algorithm: -
- FlowDefinition flow = ...
-
- // lookup start state
- StateDefinition state = flow.getStartState();
-
- // traverse to state transitions
- traverse(state);

You can construct a generic, initially empty FlowDefinitionRegistry, populate it
with flow definitions using a FlowDefinitionRegistrar, then lookup flow definitions by id.
